Dim Ran1 As Range Set Ran1 = Intersect(ActiveSheet.UsedRange, ActiveWorkbook.Sheets("机况2").Range("B:B"))

这段代码的作用是将当前活动工作表（ActiveSheet）中已使用的区域（UsedRange）与另一个名为“机况2”的工作表中的B列（Range("B:B")）进行交集运算（Intersect），并将结果存储在名为Ran1的Range对象中。换句话说，Ran1对象将包含当前活动工作表中与“机况2”工作表中B列重叠的单元格。

VBA 中Intersect(ActiveSheet.UsedRange, X) 如何设置X为B列非空单元格

您可以用以下代码来设置X为B列非空单元格：

Set X = Intersect(ActiveSheet.UsedRange, Range("B:B").SpecialCells(xlCellTypeConstants))

这样会将B列中非空的单元格赋值给X，然后与ActiveSheet中已使用的单元格范围取交集，得到最终的结果。

帮我合并以下宏程序 Private Sub Worksheet_Change(ByVal Target As Range) Dim rng As Range, cell As Range Dim arr() As Variant Dim cnt As Long Dim isCopying As Boolean ' 如果B1单元格为空，直接退出Sub过程 If Me.Range("B1").Value = "" Then Exit Sub If Not Intersect(Target, Me.Range("B1")) Is Nothing Then Sheets("点位提取").Range("C5:C200").ClearContents If Me.Range("AH34").Value = True Then Me.ListBox1.AddItem "数据已被清空 " & Format(Now, "hh:mm:ss") Me.ListBox1.ListIndex = Me.ListBox1.ListCount - 1 End If Set rng = Me.Range("B1:B2000") cnt = 0 isCopying = False For Each cell In rng If cell.Value = ":BEGIN" Then isCopying = True ReDim arr(2000) If Me.Range("AH34").Value = True Then Me.ListBox1.AddItem "开始提取数据 " & Format(Now, "hh:mm:ss") Me.ListBox1.ListIndex = Me.ListBox1.ListCount - 1 End If ElseIf cell.Value = ":END" Then isCopying = False ReDim Preserve arr(cnt - 1) Sheets("点位提取").Range("C5").Resize(cnt, 1).Value = Application.Transpose(arr) If Me.Range("AH34").Value = True Then Me.ListBox1.AddItem "数据已进行提取完毕 " & Format(Now, "hh:mm:ss") Me.ListBox1.ListIndex = Me.ListBox1.ListCount - 1 End If Exit For End If If isCopying And cell.Value <> ":BEGIN" Then arr(cnt) = rng.Cells(cell.Row, 1).Value cnt = cnt + 1 End If Next cell End If On Error GoTo ErrorHandler Exit Sub ErrorHandler: If Me.Range("AH36").Value = True Then Me.ListBox2.AddItem Err.Description & " " & Format(Now, "hh:mm:ss") Me.ListBox2.ListIndex = Me.ListBox2.ListCount - 1 End If End Sub Private Sub Worksheet_Change(ByVal Target As Range) Dim i As Integer Dim j As Integer Dim k As Integer Dim ws As Worksheet Set ws = ActiveSheet If Target.Address = "$B$2" Then For i = 9 To 40 For j = 2 To 7 If ws.Cells(i, j).Value = ws.Cells(8, 5).Value Then For k = 3 To 4 ws.Cells(i, j + k - 2).Value = ws.Cells(Application.Match(ws.Cells(i, 1).Value, ws.Range("AK9:AK40"), 0) + 8, k).Value Next k End If Next j Next i End If End Sub

可以将两个Sub过程合并为一个，代码如下：

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim rng As Range, cell As Range
    Dim arr() As Variant
    Dim cnt As Long
    Dim isCopying As Boolean
    Dim i As Integer
    Dim j As Integer
    Dim k As Integer
    Dim ws As Worksheet
    
    Set ws = ActiveSheet
    
    ' 如果B1单元格为空，直接退出Sub过程
    If Me.Range("B1").Value = "" Then Exit Sub
    
    If Not Intersect(Target, Me.Range("B1")) Is Nothing Then
        Sheets("点位提取").Range("C5:C200").ClearContents
        
        If Me.Range("AH34").Value = True Then
            Me.ListBox1.AddItem "数据已被清空 " & Format(Now, "hh:mm:ss")
            Me.ListBox1.ListIndex = Me.ListBox1.ListCount - 1
        End If
        
        Set rng = Me.Range("B1:B2000")
        cnt = 0
        isCopying = False
        
        For Each cell In rng
            If cell.Value = ":BEGIN" Then
                isCopying = True
                ReDim arr(2000)

                    Me.ListBox1.ListIndex = Me.ListBox1.ListCount - 1
                End If
                
            ElseIf cell.Value = ":END" Then
                isCopying = False
                ReDim Preserve arr(cnt - 1)
                Sheets("点位提取").Range("C5").Resize(cnt, 1).Value = Application.Transpose(arr)
                
                If Me.Range("AH34").Value = True Then

                    Me.ListBox1.ListIndex = Me.ListBox1.ListCount - 1
                End If
                
                Exit For
                
            End If
            
            If isCopying And cell.Value <> ":BEGIN" Then
                arr(cnt) = rng.Cells(cell.Row, 1).Value
                cnt = cnt + 1
            End If

                        For k = 3 To 4
                            ws.Cells(i, j + k - 2).Value = ws.Cells(Application.Match(ws.Cells(i, 1).Value, ws.Range("AK9:AK40"), 0) + 8, k).Value
                        Next k
                    End If
                Next j
            Next i
        End If

    On Error GoTo ErrorHandler
